For anyone not from Australia, or really anyone at all, because nobody in Australia speaks like this anymore, here is an explanation of some of the more mystifying slang terms and phrases in the trailer for SWDU.

“Get your hand off it” is an appeal to the listener to stop saying things that are unlikely to be true.

Nugget: Wake up to yerself Merv. You’ve been away too long. Drongo’s taken it all.

Drongo basically means a foolish or idiotic person.

Merve: Bugger me!

“Bugger me”, used in this context, is an expression of amazement or disbelief.

Burko: Darth Drongo. Trashed all the pubs and racked off with all the amber fluid. No bugger knows why he does it.

A “pub” is a bar, a place to purchase alcoholic beverages. “Racked off” means to abscond with or steal. It can also simply mean to leave. “No bugger knows.” ,in this case, bugger refers to a random, unknown person.
